If sysctl_sched_prefer_spread is enabled, then tasks would be freely
migrated to idle cpus within same cluster to reduce runnables.
By default, the feature is disabled.
User can trigger feature with:
echo 1 > /proc/sys/kernel/sched_prefer_spread
Aggressively spread tasks with in little cluster.
echo 2 > /proc/sys/kernel/sched_prefer_spread
Aggressively spread tasks with in little cluster as well as
big cluster, but not between big and little.

We are kicking no-hz idle balance when the CPU has two tasks.
It should be done only when the CPU is overutilized on
energy aware systems. This approach seems to be causing more
number of wakeups on HZ=250 systems compared to HZ=100.
Revisit the no-hz idle scheme and only send the IPI if and
when it is necessary.

The original design was to not send anything from qrtr-mhi until
a packet was received from the remote side. This would leave
enough time for the probe function to set up the driver_date.
With the new requirement to queue a hello packet (for Linux to
Linux communication), we may see the hello packet being scheduled
and sent before we can return and set the drvdata.
The changes to address the above requirement brings in a
possibility that driver_data in mhi layer is NULL sometimes.
Check device pointer for NULL in ul callback and return if
it is NULL.
Move the setting of driver data before registering it as an
endpoint with the qrtr framework.

Context aware (CA) scaling is excluisvely a pwrscale concept so move all
the probing there. This is mostly just a cut-and-paste except that the
speed_bin needs to move from Adreno to the kgsl_device so it can be
accessed from the pwrscale code.

Throughout the history of the driver the GPU platform device and the
KGSL pseudo device have been used somewhat interchangeably which is
bad. The platform device should be used whenever dealing with hardware
or kernel resources so that we can get proper cleanup during probe.
While it is still okay to use the pseudo device for log messages,
using the platform device for log messages having to do with
resources is better since you can make a more direct correlation
between the log message and the device tree entry.
